Banged Up
9.15pm, Channel 4
“Like being run over by a bus.” That’s EastEnders’ actor Sid Owen’s verdict on his first day in HMP Shrewsbury. In this bizarre new series, the former nick is reopened, populated with ex-cons and turned into what’s essentially a prison theme park so that celebrities – also including Peter Hitchens, Marcus Luther and Johnny Mercer – can get a taste of life in the big house.

The Great British Bake Off
8pm, Channel 4
Halloween dawns and the survivors of pastry week assemble. Nature is the inspiration as the bakers embark on botanical week, featuring a spice-filled signature, a herb technical and a floral dessert showstopper. That should weed out anyone who’s relying on a load of fancy icing. Hannah Verdier
The Met
9pm, BBC One
Not that the women of London have much reason to trust the Metropolitan police at the moment, but the second part of this reputation-managing series focuses on the search for a missing woman. Agnes Akom disappeared in Cricklewood – CCTV links her to lorry driver Neculai Paizan, but will he be able to explain the apparently incriminating footage? PH
Rolf Harris: Hiding in Plain Sight
9pm, ITV1
This two-part documentary begins with footage of Rolf Harris talking to Jimmy Savile. It doesn’t get much more cheerful from that point, using interviews with Harris’s victims and archive footage to show how, like Savile, Harris used the trust established by his friendly public persona to prey on children.

Jailed: Inside Maghaberry Prison
10pm, BBC Two
The governors call it the CSU, AKA the Care and Supervision Unit. The prisoners call it The Block. In practice, it’s a jail within a jail, in which the most violent and vulnerable inmates are housed, where self-harming is rife and screams echo down the corridors. In this penultimate episode, presenter Stephen Nolan finally ventures inside. Ali Catterall
The Hidden Children of Ruinerwold Farm
10pm, BBC Four
In the final double bill of this documentary, four of Gerrit-Jan van Dorsten’s children are still grappling with the horror of their childhoods. Since the trial promises no meaningful justice, it’s up to these young adults to decide where their rage should be directed. Ellen E Jones
